APPARATUS FOR MOVING .AND` SECURING` `Sli-IU'JT'.IIIERS, &c.

` Specification/ ofiLetters Patent 1\To. 7;,998, dated March 25, 1185,1.A

T0 all whom t may concern: y

Be it known that I, N. W. SrEERs, of Cincinnati, in the county ofHamilton and State of Ohio, have invented a new and useful apparatus foropening and closing window shutters from the inside of the house towhich they are attached and fastening. them at any desired point intheir semicircuit without raising the sash, whichiis described asfollows; reference being had to the annexed drawings of the same, makingpartof this specification. i i

Figure 1, is a topor birdS-eye view of the apparatus applied to awindow; the sill and shutter of the window being represented inhorizontal section. Fig. 2, is a section of the salne at the line ag ofFig. 1. Fig. 3, is a top view of the apparatus, applied vto a windowshutter hinged or hung in the ordiy their semicircuit, and secured, whenclosed,

against all danger of being opened from the outside. i

To enable others skilled in the art to `make and use my invention,`Twill proceed to de-l scribe its construction andmode` of application.i

A is the lower portion of the frame of the window.

B is a horizontal metallic screw shaft inserted in an opening, formed byan auger, diagonally through the frame, and turning in suitable metallicboxes at its ends, secured in the window. frame. These boxes may beeither connected to the extremities of a cylindrical or rectangularmetallic casing C, having` i a movable top and inclosing the screw shaftB, andfastened at its outer end to the window frame as represented inFig.

1; or the casing `may be dispensed with and E is a metallic nutsurrounding the screw shaft which passes through the same, connected bya pin at its lower part to a horizontal bar or arm F, extending througha space in the window frame to the outside of the same and attached atits outer end by a pin to a metallic plate or arm Gr, secured by screwsto the lower edge of the shutter, and extending at right angles from onewing of the lower `hinge of the shutter, which is in this case (when thehinge and apparatus are cast together to be applied to a new shutter, asrepresented in Fig. 1) secured at the extreme lower end of theshutter-the other wing of the `hinge being cast with, or otherwiseattached to the plate H to which the casing is connected, which securesit firmly to the window fram`e.` 4

In case it is desired to apply this principle of apparatus toa shutterhung on the ordinary hinges, it is formed` after `the manner of thesection marked Fig. 3, in the annexed drawings; the plates or armsGr, H,being cast distinct from the wings of the hinge.

In applying the-.apparatus to a window, it is only necessary to mark onthe lower portion of the frame the distance from the axis on which theshutter moves to the point on the outer face of the frame where the lineof the screw shaft is to intersect, and ascertain on the inner surfaceof the frame where the line is to intersect there, and after arriving atthese points to bore an auger hole through the frame suitable to receivethe screw shaft and its attachments; said hole being afterward coveredon the inside by a brass, silver, or other plate, perforated to allowthe entrance of the key D, and on the outside by the plate. The crank orkey for turning the screw shaft may be made as represented, or ofanyornamental form desired.

When it is desired to either open or close the shutter the crank or keyD is either turned to the left or right as the? case may be, causing themetallic nut E to be moved out-or in, forcing orldrawing the shutterwith it in its movements with a speed and power commensurate with theangle of the threads of the screw with the line of the shaft on whichthey are formed.

After the shutter is `once moved to the position desired, eitherentirely open, or closed, or at any intermediate point, it will be heldthere iirmly by thebar or plate F attachedV to the nut E, through whoseagency it was moved-the binding of the nut on the screw shaft B,preventing it from moving either Way, Without the screw shaft beingturned.

What I claim as my invention and desire to secure by Letters Patent isThe manner of opening and closing` Window shutters from the inside andsecuring them firmly at any point in their semicircuit by means of thehorizontal screw shaft B inserted in an opening in the lower portion 10of the Window frame, metallic nut E surrounding the same7 and the bar orplate F attached to the shutter, substantially as described.
